hi, 

I checked the official webpage of FMS delhi. it clearly mention that u need to have 10+2 +degree with 50% no criteria. after seeing your profile I calculate that u have 10+3 + degree. in this regard u may not be eligible . but I am giving u the mail id of admission cell of FMS delhi. in mail state your problem. some times there maybe another rule for diploma candidate like you.
